Re-Lock Bootloader on Galaxy Tab A T510? - Samsung Galaxy Tab A series Questions & Answers

Does anyone know if it is possible to re-lock the bootloader on the Galaxy Tab A T510? If so, would I begin with flashing back to stock firmware then disabling OEM unlock in developer options or following different steps? I certainly want to avoid bricking the device. I've searched for a solution but can't seem to find anything. Thanks!

You need to download the latest stock firmware either from Samsung or Sammobile and use Odin to flash it. DO NOT DISABLE OEM!!!! That has nothing to do with locking the bootloader. Flashing the stock ROM will do that. The OEM enable only disables the FRP lock which makes you login with the same google account used BEFORE a factory reset. If you are sure you know that account login and password, the FRP lock isn't a problem.
edit: The problem with the FRP lock is that people will often create a new google account login and password when first setting up their tablet. And because you only have to do that once, they tend to forget one or the other. Then, if they do a factory reset without the OEM enabled, they are locked out of the tablet.

Thanks for the detailed information and clarification. Your help is much appreciated!

The T510 doesn't have a locked bootloader.

No, but it does "lock" the tablet from getting OTA updates.

I have reflashed the stock firmware however I'm still receiving the following message during boot..."The bootloader is unlocked and the software on this device cannot be verified". Is there a way to remove this message? I am planning to return the device and I want to reset everything. Thanks!

Samsung SM-T580 FRP Lock

Hi everyone !
I'm actually working in an IT centre (Don't know how to call that, or to traduce to you), and I just got a customer who handed me a Samsung SM-T580 tablet who is FRP locked... I've been searching since 3 days now, trying various methods, even trying a downgrade to other versions, but no luck. I've searched on XDA to see if anyone has got the same problem, but everyone has a different build number, as mine is T580XXU2AQA2. I've seen that if the 3 finals letters/number are PG1, I'm in luck, but if they're PL4, I'm unlucky. But what about QA2 ? And what about the FRP Lock on this build ?
Thanks for help, as I begin to lose hope...

Before attempting to flash ANY ROM on a T580, you have to enable "OEM unlock" in the /Setup/Developer options. If you don't, the way to unbrick the tablet is by using the Samsung Smart Switch app via a PC.

I can't do anything as I had the tablet already locked :/ I can just access the recovery and the download mode (As well as the normal boot, but it is pointless here).
I already flashed a stock ROM via Odin, and it worked fine as it was the same version in the tablet

This one works with the latest build from PL4 to QC2 ( P= 2016, Q= 2017 ) , Android 6 ; not work with Android 7
https://www.youtube.com/watch?v=Xo9uJDDuSxw
Try it, if you can get the Assist then it will work as you can open Chrome to download Google Account Manager to add you own Google account and do the factory reset or just keep it as you are the owner now, taking full control of the tablet.

If you can go to Setting and enable the OEM Unlock, you're not FRP lock and in owner account.
FRP ( Factory Reset Protection ) is a secured method from Google prevents anyone to continue in the settings without passing the verified account steps.
Without the previous synced account ID and password, it will keep you in a loop in the setting steps.

Obviously it is to late for the OP to change to "OEM enable" setting. I was merely pointing out the cause of the problem. But it also seemed apparent that the Google account settings are unknown.
I bought a tablet on eBay that had this problem and was able to get it working using Samsung Smart Switch run from a PC connected to the tablet in the download mode.

You see this message because you're still at first page of sign in. Reset it: Power + Volume Up + Home you should get to the Recovery and do a Factory Data Reset.
If you already have original owner information, you shouldn't have any problem of setting the tablet at the step of verifying google account.
I have done FRP bypass on the SM-T580 at least 10 tablets a day, so I can say FRP of Google is a joke. I have to deal with FRP lock everyday and I only need 10 minutes to bypass it.
[EDIT] Damned font I misread FRP for FAP
Posted elsewhere, but as I'm getting rather anxious and as I'm waiting for DBT-T580XXU2BQE4-20170525170357.zip to download... I ended up with a FAP lock. I can't find out if there's any difference from FRP lock - is there any?
Also, about Smart Switch, do the instructions from https://www.sammobile.com/forum/showthread.php?t=34745 apply? Smart Switch tells me that the device is unsupported and I don't get the Device Initialization tab!
Thanks!
[EDIT2] FW downloaded. Tried to use Odin, but there are four options: BL/AP/CP/CSC. Yet the FW package has these entries:
AP_T580XXU2BQE4_CL11316739_QB13491827_REV00_user_low_ship_meta.tar.md5
BL_T580XXU2BQE4_CL11316739_QB13491827_REV00_user_low_ship.tar.md5
CSC_OXA_T580OXA2BQE4_CL11316739_QB13491827_REV00_user_low_ship.tar.md5
HOME_CSC_OXA_T580OXA2BQE4_CL11316739_QB13491827_REV00_user_low_ship.tar.md5
So which one is CP?
You only need to load BL, AP, and CSC, ignore the HOME_CSC, but it seems you're flashing the Android 7 build from Germany which no method works.
You need to downgrade to Android 6, region doesn't matter for the purpose of bypass FRP. When it's done, flash back to your original region in Android 7.
Cellular South PL4 is the build you can downgrade and bypass FRP.

First of all, thank you for your reply indeed.
Yes, I guess it was from Germany since German was its language when it first booted and it was 7.0.
So I'm downloading XAR-T580UEU2APL4-20170407113933.zip (Cellular South PL4) and flashing it with Odin, but once it's done, how do I flash 7 again? Use Odin with the initial BL/AP/CSC that I got?
Again, thank you!
[EDIT] Oh yeah, 6.0 flashed successfully and I'm off FRP lock!!!! Thanks so much... Now I guess I turn on OEM enable in Dev options and flash BL/AP/CSC in Odin?
No need to flash back if you want to keep current US build if it has your prefer language.
However, it's now US tablet, it only update the latest one from US build.
No need to turn on OEM unlock if you know your own Google ID and password.
If you like, flash the Europe build as it has more languages than US one, the same way as you downgrade firmware: load BL, AP, and CSC to Odin.
You're right. I was asking because I thought I'd have lost OTA, which was not the case - device updated OTA to 7.0 so I then proceeded and rooted it again. *Now* OTA is dead, but I'm good.
I was thinking, probably, than on Samsung devices tripping Knox would disable OTA.
Thanks for your reply once more
Tripping Knox doesn’t disable OTA but if the status of firmware is Custom, you won’t be able to update software. I have some tablets which have Knox count more than 1, they update normally because I run stock firmware

Yup! I'm learning by doing
I guess that having an official FW but custom recovery equals to Custom, correct? Which means if I reflash original OTA will be back?
In the setting, About Tablet, Status, if the device status is Official, you have no problem of update via OTA.
Or in Download Mode, if the System Status is Official. I believe your system is Custom if having custom recovery.
Rooted device will become Official if you flash back the stock firmware , however the Knox counting is not rolling back to zero.
Yup, I did know about Knox (that would defeat the purpose, right? ).
If I'm not mistaken flashing original FW will erase data, no? So I'll save it for when there's a decent Oreo ROM out there. Then again, it won't be Original even then so I guess I'm off that road, but I don't think Samsung will be releasing any new OTAs any time soon so there's no meaning in it, surely?

[A3 2016] Recover data from FRP Lock bootloop?

No idea what possessed me to do it (it was late), I unchecked "OEM Unlock", and bricked my phone.
(Android 5.1.1, stock recovery, rooted)
It's stuck in a bootloop with the red message "Custom binary blocked by FRP lock."
I've read many other posts stating that flashing stock firmware will unbrick the phone. That's great, the hardware can be saved. But I need the data; contacts, txts, photos.
What are my options?
Is there any way around FRP lock? I understand tit's intended as a security feature, and basically only happens when people do idiot stuff like unchecking OEM Unlock. So I doubt many devs/hackers have put much focus on developing workarounds.
Theoretically, Samsung may have the capacity to unlock the FRP lock. Is this a thing? Does anyone know anything about sending it to a Samsung tech center? Probably they would have difficulty guaranteeing the phone sender should have rightful access to the phone, so perhaps they provide no pathway?
@ashyx, I've read your posts, you're frankly a wizard. Any thoughts? Thanks
Frustrated with myself,

Really? Many posts I've seen have noted that "all user data will be deleted".
Do I just use ODIN, and flash AP? No app, or user data will be erased, or formatted like that?
A few mention "Initializing with Smart Switch"; I haven't done that before. Is that different than flashing firmware?

Searching for that question directly, it seems like flashing a ROM (e.g. stock firmware) will not directly erase user data; downloads, photos in DCIM, etc.
But, sounds like any user-installed apps will be erased (so any internally stored data would be lost).
And, data stored in system apps would be lost, too; e.g. tabs that were open in Chrome.
There's no way around the FRP lock, eh?
Here is Samsung's statement about FRP (Factory Reset Protection)
It describes the Google account "protection" features, but doesn't really describe how FRP lock leads to bootloops.
https://www.samsung.com/us/support/frp/
Factory Reset Protection (FRP) Feature
What is Device Protection, or Factory Reset Protection (FRP)?
Android™ devices provide built-in security features you can use to protect your device and information, including screen locks and data encryption. Data protection, or Factory Reset Protection (FRP), is a security feature on Android devices with Lollipop 5.1 and higher.
FRP is automatically activated when you set up a Google™ Account on your device. Once FRP is activated, it prevents use of a device after a factory data reset, until you log in using a Google username and password previously set up on the device.
How does FRP work?
When you perform a Factory Data Reset, all settings are returned to the factory default settings. All data is erased, including files and downloaded apps.
If you have a Google Account set up on the device, FRP is active. This means that after the reset, you'll be required to log in to the Google Account using the username and password. If you have multiple Google Accounts set up on the device, you can log in using any of the accounts.
If an unauthorized person tries to reset the device by another method, the device would still require log-in using the Google username and password. This means that if your device is lost or stolen, another person would not be able to reset it and use it.
What do I need to know about FRP?
If you want to reset your device to factory defaults, make sure you know your Google Account and password, because you'll need to log in at the end of the reset.
If you want to reset your device to factory defaults, but don't remember your Google username and/or password, you can do one of these:
Check your device’s Account settings for your account name, and reset your password via the device or at www.google.com.
It can take 24 hours for the password reset to sync with all devices registered to the account.
Remove the account before you reset the device.
If you already reset your device, but don't remember your Google username and/or password, the device can't be used. In that case, you can do one of these:
If you know your Google username but can't remember the password, you can reset your password on the device, or at www.google.com. It can take up to 24 hours for a new password to sync with all registered devices. After 24 hours, you can try logging in to your phone with the new password.
If you have multiple Google Accounts, and you can't remember which Google Account you set up on your device, visit https://www.google.com/android/devicemanager.
Log in with your Google username and password and check the list of devices registered to the account. If you don't see the device listed on the account, it means the device is registered to a different account. Use the same process to check for devices linked to your other Google Accounts. When you find the registered account, use it to log in to your device.
If you can't remember any of your Google Account information, you can send your device, along with proof of purchase, to an authorized Samsung Service Center. Samsung has special tools to reset the phone to factory defaults with no protection enabled.

Looking for a Samsung Authorized Support Center, apparently there are ZERO listed around Omaha, NE.

There must be ASC's somewhere; I'm hesitant to mail the phone away because I think the tech will just wipe it. The whole point is to maintain the data :-/
What do I need to flash to remove "Custom binary" ?
Will flashing the bootloader back to stock unlock the FRP lock?
That's BL throuh ODIN, right?
Do I have to flash AP ?
Won't that remove all user apps and their data, and any user data associated with system apps?

Not being funny, but you're panicking over nothing. I can pretty much guarantee you will NOT lose any data, apps or settings. The DATA partion is untouched by stock firmware.
Just flash the whole stock firmware(not repair firmware) and you'll be fine.
If you're super paranoid about losing data then just flash the AP part.

It will be exactly as it was before. Nothing will change.
There are only 2 binaries that need flashing, boot and recovery, however unless you are flashing the exact firmware you had previously you may get compatibility issues, so it's best to just flash the whole firmware.

I've never found any discussions about how to solve the frp lock bootloop, with the intention of preserving user data.
If you will indulge me a bit more, I'd like to learn, test, and then share this for others.
Do you know exactly Custom binary blocked by FRP lock ""security" works?
Where is the flag that gets tripped?
In order to solve this bootloop, technically just Boot loader and Recovery need to be flashed (the exact versions must be used, or comparability issues can occur).
Bootloader should be simple enough: BL is one of the specific upload choices in Odin.
Recovery is a .bin that's contained with the AP.tar, correct?
Is it possible to specifically flash only the Recovery?

No, I didn't mention the bootloader, that is a different part of the firmware. The boot and recovery images have a .img extension and should be flashed under AP.
It is the bootloader that detects non official firmware and trips the FRP flag. If it's disabled in settings via OEM UNLOCK the bootloader ignores it and allows the device to boot.

Sh!t, sorry, boot.ing /= bootloader. Rookie mistake. #StillLearning
OK, so boot.img and recovery.img should both be contained within the AP component of stock firmware.
I can just flash those two, can't I?

Is there any non-GUI way to toggle the OEM UNLOCK?
Bootloader? Download mode? Recovery? Fastboot? ADB?
I assume not, since that might be a "security" risk. And also, if there were, problems like this would have solutions posted mentioning how to do that.
Sh!!!!!!!t... I was thinking I would have screenshots of the exact build that's loaded on my phone. That way I can find the right stock firmware.
Seems those screenshots are still in the phone, didn't get moved to external memory
All I know for sure is it's Andorid 5.1.1, but that probably isn't specific enough to get the exact right boot and recovery images.
I intend to flash the boot.img and recovery.img to my phone. Hopefully, this will avoid any data loss, while clearing the FRP lock bootloop.
I got the stock firmware for Android 5.1.1 for my Galaxy A3 (2016) (SM-A310M) here:
https://www.sammobile.com/firmwares/galaxy-a3-/SM-A310M/TTT/download/A310MUBU2APE2/73991/
This set of instructions says to extract the .img file(s) to flash, then just .tar them up using 7zip, and flash it as AP in ODIN.
http://howto.highonandroid.com/sams...extract-stock-recovery-from-samsung-firmware/
But... this one says to use Unified Android Toolkit, option ‘8’ (Create an Odin flashable tar), and then flash with ODIN.
https://skipsoft.net/flashing-a-single-partition-i-e-system/
Fortunately, I have a Galaxy A3 (2017) (SM-A320Y), which I was just about to upgrade to for my daily driver. It's blank, running Android 7.0, so it means I can test this process, see if data is preserved, with almost no risk to actual data. Got that firmware here:
https://www.sammobile.com/firmwares/SM-A320Y/COO/download/A320YDXU1BQH2/189605/
Ironically... I don't yet have a great method to intentionally trip the FRP lock bootloop
I think rooting and then unchecking OEM Unlock should do it (that's what wrecked my A310M)

Could you help me to get access to my data? I'm running port of S8 on my S7 and got bootloop. Someone told me that even if I'll flash AP only I might lose my data because of difference in the way the memory is formatted.

If they're both stock based firmware then you can just flash the stock S7 firmware. Data should remain untouched.
Hi
I am just stuck with the same problem. I have downloaded the latest Stock ROM. But unsure which options to select in ODIN and what files to select.
I presume only select AP. Also, hope I will not lose any data.
Please help me out.

Samsung s8 software problem

So i have an Samsung S8 SM-G950F. I made a factory reset on it but because i forgot my synced google account username and password on it i wanted to flash the same software again on it so i can use it again but forgot to click the OEM Unlock option. Now i flashed custom binary on it and with ODIN i tried to flash my new firmware but nothing happened. And when i enter in the custom binary in developer options there is no OEM Unlock option? What can i do. They told me the only way is to change the main board of the phone. Is this true,i mean the boar costs as much as the phone ...

You have to wait for 7 days without the phone dying or being turned off, then the oem unlock option will appear, I take it you flashed oreo?

So you are on nougat right now, ignore what I said then about waiting 7 days, as far as I know it applies to oreo, I mean you can wait and see if you want but apart from that, have you nor acceded your gmail account on a computer or laptop or anything? Maybe try to recover the username and password that way, my Google account is my main email account so that makes it handy for me when issues like this occur, not sure what else you can try

How to unlock oem on my galaxy tab 9.7?

As in the title, it doesn't show the option to unlock oem. I tried changing time, updating etc. Tablet is on version 7.1.1 right now.
Have you unlocked developer options?

First of all, you don't "unlock oem". You enable "OEM" mode. And if it isn't an option in Developer options, then it probably isn't needed. All enabling OEM does is disable the FRP lock. (Factory Reset Protection) If the tablet is protected, it just means you will need the Google Account info, login and password, to get back into the tablet after a Factory Reset. If you are in doubt, just remove all of the current google accounts before resetting.

I have no idea what stage you are currently but if unlocked the bootloader, then that already caused a factory reset. If you did it right and flashed the current stock ROM, and then rebooted, connected wifi and skipped the rest of the setup, as the instructions said, then there shouldn't be a google account. Then when you enable Dev mode, you are ready to boot to download and flash the LOS ROM with Odin. That will also flash TWRP.

There are instructions in the "Guides, News and Dicussions" thread.
edit: I just noticed that you say your tablet is 9.7". Just what is the model? If it is an older model, it won't have a locked bootloader. But you'll have to find a ROM for your tablet and follow the instruction for it. Every model Tab A has its own custom ROMs and you can't use ROMs for any other model.

google account locked

Is it poss to get passed Google Verify lock as I've got a g950f from my late mothers but don't know any of deets for log ins. Can't access setting to allow ADB either
factory reset .... but you'll lose all data .....
Factory reset doesn't remove the frp lock
Okay, we removed a frp-lock once by using Odin. The best you can do is search for the right stock Rom and flash this with Odin, but you need to access download-mode on your phone which must be possible also with a phone with frp-lock, because it is there where the frp-lock is shown. For as far as I know, also recovery-mode should normally still be available.
